AIR-SHIP.

Specif cation of Letters Patent.

' Application filed November 13, 1908. Seria1No.462,42 5.

T all whom it may concern: Be it known that I, CHARLs J. BERTHEL, a subject of the Emperor of Germany, and a resident of Pinetown, in the county of Beaufort and State of North Carolina, l'iave invented certain new anduseful Improvements in Air-Ehips, of which the following is a specification.

My invention. is an improvement in air ships'and consists in certain novel conv structions and combinatio'nsof parts hereinafter described and claimed.

Referring to the drawings forming a part hereof Figure 1 is a section on the line 1-1 of Fig; 2. Fig. 2 is a plan-view, and Fig. 3 is a view looking in the direction of the arrow in Fig. 1.-

The present embodiment of my invention comprises atube 1, open at each end, and provided adjacent to each end with a cross bar 2, having a bearing 3, in which is journaled a shaft 4. The shaft 4 is provided at each end within the tube with a propeller 5, and a suitable motor 6 is supported within the tube, and is connected with the shaft. The tube is provided with a seat 6*, for the aviator, and with runners 7 on its lower side, upon which it may rest. when not in flight; The tubeis also provided in its upper and under sides with doors 8, and upon each side-of the seat with openings 9, normally closed by a transparent covering. Near the rear end of the tube and transversely thereof, is ournaled a shaft 10, with which is connected a rudder '11, and the upper end of the shaft is provided With-a pulley 12, over which,passes a cord 13, the ends of the-cord extending over a second pulley 14, and through an opening 15 in the top of the tube to a point adjacent to the aviator.

At the front end of. the tube is arranged a horizontal shaft 17, with which is connected a front rudder 18. A double pulley 19.is

J journaled above the shaft 17 and a pulley 20 -is journaled below, and cords 21 extend from the front of the rudder, and around the pulleys 19, 20, and over a pulley 23 through the opening. 15 to a point adjacent the seat of the aviator. A plane 24 of suitable size and material is connected .With the upper surface of'the tube, and extends upon each side thereof, as at 25, 26 forming wings for- I steadying and supporting the tube.

1 -It" ill -be-observed hat when the shipjisnot in flight, the tube takes an inclined position as shown injFigs,1 and.3,:with the the rudder 11.

front end elevated. When the motor is started and the propellers rotate, the machine will be lifted, and will move upwardly on an inclin'ed plane, the rising and falling movement being governed by the rudder 18, which is operated through. the cords 21. The ship is guided in a horizontal plane by It will be seen that the of the aeroplane spread a greater distance transversely to the line of flight than the fore and aft distance. This follows the analogy of the wings of a bird andis founded upon a true principle of" physics essential to all successfulaero planes, which secures a short transverse.

impact (if the wings upon the relatively still air, whose inertia gives the resultant'upward pressure to buoy up the aeroplane and allows the quick clearance of the air in the rear. It will also be seen that the fore and aft dimensions of the wings are exactly equal to the lengthof the cylinder, the edge of the aeroplane wings in front terminating at the front edge .of the cylinder, and the edge of the aeroplane wings in the rear terminating at the rear edge of thecylinder and that the distance from the tip of one wing to the tip of the other is greater than the length of the cylinder or tube. I claim: I

1. A device of the class described comprising anopen ended tube provided with lateral wings, a shaft journaled therein at the longitudinal center thereof, propellers at each end of the shaft within the tube, a motor within the tube and connected to the shaft, a substantially vertical rudder at one end ofthe-- tube, a sub stantially horizontalrudder at the" other end, and means for operating said rudders from the interior of the tube.

2. An airship of the class described comprisin an open ended tube provided with latera wings, a propeller in the tube, a substantially vertical rudder at one end, a hor1- zontal rudder at the other end, and means for operating said rudders from the interior of the tube.

3. In an airship, a tube having lateral.

wings, propelling mechanism within the tube, guidihg means ateach end of the tube, and means for operating said guiding means from within the tube.

, 4.. An aeroplane comprising a central tube of circular cross section having two rigidly attached wings extending from opposite sides of the same, the. Wings having, their greatest dimension at right an his to the longitudinal axis of the t e an of a greater length than the tube. V

5. An aeroplane comprising a central tube of circular cross section having two rigidly .attached wings extending from 0 posite sides of the same, the wings havin t eir greatest dimension at right angles to t e long1tudinal axis of'the tube and of greater length than the tube and said tube belng formed as a true cylinder with both ends open.

6. An aeroplane comprising a central tube of circular cross section having two wings extending from opposite sides of the same, the wings having their greatest dimension at right angles to the longitudinal axis of the tube and said tube being formed as a true cylinder both ends 0 en, the circular front end terminating at t e front edge of the aeroplane wings and the circular rear end terminating at the rear edge of the aeroplane wings.

7.- An aeroplane comprising a central tube of circular cross section having two wings extending from opposite sides of the same, said tube being formed as a true cylinder with both ends 0 en the circular front end terminating at t e front edge of the aeroplane win s and the circular rear end terminating at t e rear edge of the aero lane wings.
